1-D TIRE APPARATUS
First Claim
1. A tire mountable apparatus, comprising:
- a substrate having a first surface and a second surface; and
a pair of terminal/support elements extending from said first surface,wherein said first surface has length L and width W, wherein L>
2W, and W<
the length of arc subtended along the inner surface of a tire corresponding to 5°
of rotation measured from a line extending from the center of rotation to the inner surface of an unloaded tire inflated at rated pressure, andwherein said pair of terminals extends from said first surface in a line 90°
±
10 °
to a line in the direction of the length L, and the line 90°
±
10°
to the direction of length L identifies the direction of rotation of a supporting tire.

Abstract
Disclosed is a tire mountable apparatus and methodology for mounting devices within a tire. In certain embodiments a signal generator may be mounted to the tire to generate signals based on changes in the radius of curvature of a tire. A piezoelectric sandwich and/or a substrate is/are provided having a length and width based at least in part on tire dimensions and positioned in the tire such that the longer length dimension is positioned laterally with respect to the width of the tire. The sandwich and/or substrate is/are sized such that the width dimension provides substantially no response to changes in the circumferential radius of curvature of the tire so that the length dimension defines the primary bending direction while the width dimension provides a strain free mount for associated devices.

16. A method for reducing strain in a tire mounted assembly, comprising:
-
providing a substrate having a first surface and a second surface, wherein said substrate has length L and width W, wherein L>
2W, and W<
the length of arc subtended along the inner surface of a tire corresponding to 5°
of rotation measured from a line extending from the center of rotation to the inner surface of an unloaded tire inflated at rated pressure;providing a pair of terminal/support elements extending from said first surface; positioning said pair of terminal/support elements in a line 90°
±
10°
to a line in the direction of the length L; andmounting the substrate in a tire so that the line 90°
±
10°
to the direction of the length L is aligned in the direction of rotation of said tire ±
20°
, whereby strain on the tire mounted assembly is effectively limited to one direction. - View Dependent Claims (17, 19, 20, 21, 22, 23, 24)
